I've also found out some missing functionality of AirBlue Sharing.
As opposed to just NFC'ing the images to an Android device, sending a photo to an iDevice using AirBlue Sharing has a downside: the current (1.4.50) version of AirBlue Sharing doesn't transfer the EXIF data of the image when saving the received file to the Camera Roll. (No such problem on Android there, the full EXIF data remains accessible in the stock Gallery app after transfer.)
I'll talk to the dev of AirBlue Sharing on this matter. I've implemented both full EXIF metadata saving and also location + compass saving in my own camera-related AppStore apps. Saving this info is pretty easy in iOS when exporting images to the Camera Roll.
